25HP on a 4.5m SIB - speeds?
Hi guys (and gals).
Following an awful start to my first venture with a boat when I was missold a 15HP Mariner, I have managed to win an auction of a 25HP Johnson and will hopefully be collecting in next weekend. My question is, what sort of speeds would I get with a 4.5m SIB (Ali floor), 25HP with 4 adults and about 15kg of kit? Will it plane? The max HP on the transom is 30HP so 25HP will do nicely! Cheers in advance!
